Normal imaging characteristics of dextranomer/hyaluronic acid copolymer injection on MR imaging. MR images in a 71-year-old man status post dextranomer/hyaluronic acid copolymer injection demonstrate a multiloculated T2 hyperintense (A) and T1 isointense lesion (B) on axial images. DWI (C) and ADC (D) images demonstrate no evidence of restricted diffusion. MR images in a 13-year-old girl 1 month status post injection demonstrate a multiloculated T2 hyperintense (E) and a T1 isointense lesion on axial images (F). No evidence of peripheral enhancement is seen on postgadolinium T1-weighted images (G). No evidence of restricted diffusion (H) is seen.
